Sabic introduces a family of eight Thermocomp materials designed for large-format additive manufacturing. The materials are reinforced with carbon or glass fibers for strength and can be used in tooling, aerospace, automotive and defense applications.

The materials are based on four of the company’s amorphous resins: ABS, PPE, PC and PEI. The ABS-based compounds are designed to provide easy processing, low warpage and good print surface quality, making them candidate materials for a broad range of applications, including thermoforming and vacuum forming.

PPE-based compounds are said to offer lower thermal expansion, hydrolytic stability, a higher strength-to-weight ratio and higher temperature performance when compared to ABS.

PC-based compounds are said deliver higher stiffness, higher temperature performance and higher throughput compared to ABS and PPE, as well as ductility and a smooth surface finish.

PEI-based compounds, developed from Sabic’s flame-retardant Ultem resins, are designed to provide low thermal expansion, high temperature performance, a high strength-to-weight ratio, high modulus and low creep.

Each of the Thermocomp AM materials is reinforced with carbon or glass fiber, depending on the degree of stiffness and dimensional stability required. They are said to exhibit good creep behavior versus semi-crystalline resins, reduced deformation under constant pressure, greater dimensional stability and less thermal expansion during part use.
